- Equation 1 : HA + H2O -> A- + H3O+ weak acid conjugate base (a) Using Equation 1 as a guide, write an equation for the reaction of acetic acid (CH 3COOH) with water.(b) Identify the conjugate base of acetic acid in the reaction equation.arrow_forwardConsider the following chemical reaction: HCO3 + HCI Which one of products is a conjugate base? O HCO3 OHCI O H₂CO3 O cr = H₂CO3 + CI.arrow_forwardAcid-Base Equilibria Many factors contribute to the acidity of organic compounds. Electronegativity, resonance, induction, hybridization, aromaticity, and atomic size, all play a role. In the following comparisons, you are asked to identify the factor(s) that would be most important to analyze when predicting relative acidity, and then to predict the trend in acidity and pKa values. For each of the following pairs of compounds answer the following two multiple-choice questions. 1. What factor(s) are the most important to consider when predicting the relative acidity of the two compounds? a. Electronegativity of the atom possessing the hydrogen. b. Resonance stabilization of the anionic conjugate base. c. Inductive stabilization of the anionic conjugate base. d. Hybridization of the atom possessing the hydrogen. e. The atomic size of the atom possessing the hydrogen.arrow_forward
